Application and my 2a 1996-v Serial Ifo-,327.755,

To all whom it may concern:

Beit known that I, FRANCIS JERDONE, Jr., a citizen of the United States, residing at Chicago, in the county of Cook and State of 'Illinois, have invented certain new and useful Improvements in Car-Bolsters'; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

vThis invention relates to bolsters for car structures, and h as for an object to provide a bolster of improved form and added strength embodying economy of construction.

A further object of the invention is to provide in a car-bolster improved means for connection with a single center sill of the car structure.

A further object of the invention is to provide in a' car-bolster improved means for connecting and attachin the usual and customary truss-rods when esir'able.

With these and other objects in view the invention comprises certain other :novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed. l.

In the drawings, Figure 1 is a view of the improved bolster in side elevation. Fig. 2 is a top plan view of the im rovcd bolster. Fig. 3 is an end view of the olster seen on arrow 3 of Fics. 1 and 2. Fi 4 is a transverse sectiona view line 4 4 of Fig. 1. Fig. 5 is a detail fragmentary ,view of the central ortion of the bolster structure, showing tie center beam yin section and the preferred manner of connectg in the bolster and beam.

n its preferred embodiment the im roved bolster forming the subject-matter of t is application com rises a bolster-body substantially elliptica in general outline and comprising a Web 10, surrounded by a flange 11 the said iange standing out and dis osed substantially at right angles to the we and upon opposite sides thereof, as shown particularly in Figs. 2 and 4. The bolster-body may be formed in any approved manner, as by stamping, but 1s preferably a steel casting formed integral throughout and also preferably formed with a plurality of openings, as 12,inthe web 10.

At its center the web portion 10 is formed with an opening 13, shaped to embrace and of the bo ster, taken on fit the center beam of the car structure, (here Shown t5 the Lbeam 14,) and with-thickened portions 0.1' bosses l @11d 16 surrounding the .openin 13 for the purpose 0f Strengthemng me we.' adjacent the o eninv The webs 15 and 16 are provided wit.. a openings, as 17 and the bester is rigidly Secured to the Lbeem 14 by means of angleirons 1S and 19, disposed within four angles formed by the web of the bolster and the I-beam and secured by rivets 20. To further reinforce the opening for the I-beam 14, the swivel-plete 21 is riveted rigidly to the under side of the Harige 1.1 and extends lon= gitudinally of the bolster across the opening by rivets 22. A The under ange .Of the bolster is also provided with downwardly-Offset 01- tions 23 to accommodate the usual anti iction-rolls to perm'it the bolster to Qscillate -upon the truck. At the opposite ends the bolster is provided -with an outer or end plate 23, spaced from an inner plate 24 to define an opening '25, into which the eye of a truss-rod 26 may be inserted and secured by means of a bolt 27 through either one of the openings 28. The openings 28 are for-med upon each side of the web 10, so that the bolster may be disposed upon the center beam interchangeably, althou'h but one of the said openings is usualla employed. The openings 28 are provi ed wlth encircling bosses 29 for the purpose of stren thening the said openings and roviding a caringsurface for the head of t sociatd nut.

At its opposite ends the bolster is provided with a normally horizontal plate-like portion 30, adapted to support beams 31, which form the side'sills of the car and are provided with rivet-o enings 32 to receive rivets, as 33, by which vhe angle-iron side sills 31 are secured rigidly to the bolster. y

For association with the form of bolster here shown a metal floor is which, owever, forms the subject-matter of a oopending a lication, bearing Serial N o. Y 327 ,7 53 ,filed Jliiy 25, 1906, and 1S not herein claimed. The web 10 of the bolster may be further provided with o wings-35, through which maybe inserted the usual train-pipes for the air-brake system and may of course be provided with such other openings 'as the particular system installed may render dee bolt 27'and its asl preferably used' and supported upon transverse beams 34,v

liirality of' rivetand is secured nany ap roved manner, as

IIO

enable, being preferably encircled by bosses 36, so that the openings so formed do not weaken the web structure.

The connection between the bolster proper and the' side sills 31 is further strengthened and rigidity added by means of a tie or gusset plate 37, rigidlyl secured `to lthe upper flange li of the bolster'and ben-t to accommodate 'theloyver flange of the angle-iron 3l and eX- tending upward along the vertical iiange and reveted thereto,as shown particularly in Fig l. bile tbe bolster here described is shown for connecting the bolster in association with an I-beam as the single center beam of the car, it will be obvious that a single center beam of any other form may` tral opening and definingd the limits of the bolster, means adjacent t e central opening to a frame structure, and means formed at the ends of the bolster for connection with a truss-rod.

3, In a bolster, a body structure, spaced plates at the ends of the body structure and defining openings upon opposite sides of the body structure positioned to receive and engage a truss-rod.

ll. In a bolster, abody structure, spaced vertical plates formed at o posite ends of the structure, and extending aterally upon opseance posite sides of the structure, and with regis- 3.o

extending truss-rod upon opposite sides of the bolster.

6. In a bolster, a Webbed body structure provided with a surrounding flange, and having a vertical central opening extending substantially the vyidth of the body, and reinforcing means secured to the flange and spanning the interval of the opening at the lower side. v

7. In a bolster, a Webbed body portion having a surrounding flange and with a central beam-receiving o eningi extending substantially the Width o the web, and reinforcinfr means carried by the flange above and be oW and spanning the interval of the central o ening.

8. n a bolster, a laterallyextending body portion, means for securing side rails upon the opposite ends of the bolster, and a gusset proportioned to be secured to the bolster and siderail and to rigidly connect the two.

y9. In a bolster, a' webbed body portion surrounded by a limiting flange, means for securing side rails to the opposite end of the bolster, and a gusset proportioned to be se cured to and rigidly connect the side-raillimiting flange.

In testimony whereof I affix my signature in presence of tWo Witnesses.
